Description
Technical field
Transformer framework is the utility model is related to, more particularly to for safety can be met in high-power AC-DC Switching Power Supplies
It is required that electronic transformer skeleton.
Background technology
Existing AC-DC switching mode power supply transformers skeleton is typically made up of the wrapping post with centre bore and terminal board.Such as Fig. 1 institutes
Show, including the wrapping post 01 with centre bore, the overhead gage 02 and lower baffle plate 03 that stretch out along the both ends of wrapping post 01；Upper gear
The both sides of plate 02 are symmetrically arranged with left location-plate 04 and right location-plate 05, and it is vertical that left location-plate 04 and right location-plate 05 prolong overhead gage 02
Upwardly extend and be in class " V " shape structure；The both sides of lower baffle plate 03 are symmetrically arranged with primary terminals platform 06 and secondary terminal board 07, primary
The lower surface of terminal board 06 is vertically provided with terminal 08 evenly and at intervals, and the secondary lower surface of terminal board 07 is vertically provided with end evenly and at intervals
Son 09.For such a skeleton due to symmetrical, mould is simple, therefore is market male model product, and buying is easy, but due to left location-plate
04 and right location-plate 05 fill the cross-sectional area of magnetic core in class " V " type structure, the centre bore for wasting wrapping post 01, cause to assemble
Magnetic core area is small, magnetic flux can not maximize so that the power of transformer can not maximize in the volume of restriction, be unfavorable for
Product minimizes.
As shown in Fig. 2 for another existing transformer framework, it is that the both sides of overhead gage 02 are symmetrically set with Fig. 1 differences
The left location-plate 04 and right location-plate 05 put prolong overhead gage 02 and extend vertically upwards and be rectangle structure.The electronic transformer bone
Frame coiling litz wire finishes up bending as shown in figure 3, because left location-plate 04 and right location-plate 05 are rectangle structure, magnetic core area
It is maximized, but in the very thick litz wire of coiling, line can be reduced in the case where height is certain, during coil ending bending
Enclosing the number of turn so that the power of transformer has declined, again such that the power of transformer can not maximize in the volume of restriction,
It is unfavorable for product miniaturization.
Existing technical staff thinks that 05 two kinds of structures of Fig. 1 and the left location-plates 04 of Fig. 2 and right location-plate cause transformer
Power can not maximize in the volume of restriction, therefore in order to meet power needs, and influenceed by symmetrical expression inertial thinking,
All it is selection one of which structure during design, otherwise the diameter of wrapping post 01 is increased, otherwise lengthen the height of wrapping post 01.
In addition, for high-power AC-DC Switching Power Supplies, in order to meet design requirement, technical staff needs designing high-power
Transformer, power is bigger, magnetic core to the creep age distance between transformer framework pin terminals is also required to bigger, its magnetic core to transformation
Device skeleton pin creep age distance schematic diagram is as shown in figure 4, wherein shown in thick line be magnetic core to transformer framework pin terminals
Between creep age distance, technical staff's generally use directly increases the height of transformer framework, the width of terminal board during conventional design
To meet the requirement of power and creep age distance, this would generally allow is increased using the product shape of these transformers, is unfavorable for product
Miniaturization.
Transformer framework industry has formed standardized production, in the market in the presence of substantial amounts of male model product, prior art
Personnel are for cost-effective and standardization consideration, the usual skeleton for just directly selecting market standard in Design of Transformer,
However as the change in market, AC-DC Switching Power Supplies, high-power, miniaturization has turned into the direction of future development, AC-DC switches
Important material electronic transformer skeleton in power supply, it is necessary to the design of high-power compact is first carried out, to meet industry future
Growth requirement.
Therefore, in certain volume, magnetic core area, number of turns and creep age distance are ensured to greatest extent, so as to ensure
Power demand has become one of industry problems, and prior art also generates very more solutions, and typical scenario is as follows：

2nd, Patent No. ZL 201210338985.X, entitled《A kind of combined type adjustable transformer skeleton and use the bone
The transformer of frame》Patent of invention, the patent passes through body frame and plug connector and coordinates assembling and the adjustment of plug connector setting angle, increase
Electric clearance and creep age distance is added to meet standard requirement；
Above two technical scheme solve the problems, such as safety essence or lengthen terminal board width or height, only for
Do not increase the volume of transformer, it is not so direct that it, which widens/increased the scheme of terminal board, but structure is more special
Very, but this also make it that structure is complex, causes wire winding complicated, is unfavorable for cost declining.
